In this lesson, we will deepen our skills in quantitative research methods to: Explain how survey tools can be used to evaluate your campaigns impact. Describe the value of sample size for your quantitative research and measurement of impact. Define representative sampling and identify the key factors in bias.
Quantitative Research Review of Research Questions and Research & Planning Timeline (15 Mins) Discovering Key Concepts Representative Sampling, Sampling Size and Design (1.5H) Reading and Group Workshop (1.5H) Revisiting Your Research Plan and Rubrics (1.5H) QUANTITATIVE RESEARCH SESSION OUTLINE
Quantitative Research Research Planning Process Conceptualization (1) Research Design (2) Data Collection (3) Data Analysis (4)
Quantitative Research Scope : target population, or the group of people that you want to study with the survey. Comparison Site Conceptualization (1)
Quantitative Research SURVEY SAMPLING RANDOM SAMPLING Define target population Choose a sample frame Stratified sampling Research Design (2)
What is Statistics? A method for collection and interpreting quantitative data Collection: Data is collected the right way Analyzing: Mathematical tools or models for interpreting data
Statistics and your Survey: Sampling Usually impossible to interview everyone in your area (at most sites) so you take a sample A sample is a subset of your TA that is used to represent the whole group. If they represent the WHOLE group then…. You want to select a representative sample
Quantitative Research Why is representative so Important?
Quantitative Research What is representative?
Quantitative Research What is the full spectrum?
Quantitative Research The Normal Distribution
Quantitative Research Who represents your Target Audience?
Quantitative Research Designing your Survey: Representative Sampling *Representative: The survey is designed such that the frequencies (or percent types of people) sample reflect the true frequencies (or percent types) in the population Age range Gender Employment Socio-economic status
Quantitative Research Representative sample step: Determine your sample scope Where do your target audience or audiences live?
Quantitative Research Sampling and Campaign Decisions How many samples do I need to collect?
Quantitative Research Key Concepts Confidence Interval : reflects the range of numbers that reflect the true value
Quantitative Research Confidence Level: tells you how sure you can be you that your sample is generally representative of your population. NOTE: Dont worry about this – just know that we use a 95% confidence level and it tells you how confident you are that your estimate (of knowledge e.g.) is accurate
Quantitative Research Select your Sampling Strategy Design a truly random sample How many samples do I need to collect? Sample Size Calculator: Population Size: ? Confidence interval: 5% (Rare standard) Confidence level: 95% (Rare standard)
Quantitative Research How many samples do you need here?
Quantitative Research Where can you go to collect your data? Door to Door Any Other Defined Place Pre-Determined Location Central Location Data Collection (3)
Quantitative Research Sample Size Factors to consider Determining your Sample Size Confidence Intervals Population Size Sample Size Estimator
Quantitative Research Tips for Data Management Here are some key tips for staying on top of quantitative data: 1.Create a plan 2.Create a data input process 3.Stay Organized 4.Write legibly, neatly, clearly 5.Document the choices 6.Get help

Quantitative Research In this lesson, we will deepen our skills in quantitative research methods to: Explain how survey tools can be used to evaluate your campaigns impact. Describe the value of sample size for your quantitative research and measurement of impact. Define representative sampling and identify the key factors in bias.
